13: The Colonies in Revolt is an operational simulation of the American Revolutionary War from late 1775 (the siege of Boston and the two Canadian expeditions) through the end of 1781. The British player must try to stop the revolt by trying to control half a continent. Included are a 16 page rulebook, 22"x34" map, 200 counters, and various player charts and tables. The British player wins in one of two ways. If the year is 1775 or 1776, the British player requires control of a limited number of objectives (Canada, Boston, New York, Philadelphia, Charleston, and one area of operations). If the game continues to 1781, the British player must control New England, the Middle Colonies, the South, and either Canada or the Western Territories. If the British do not attain these objectives, the American player wins.
